Whirlpool Sensor Calibration Error

Freezer temperature display inaccurate compared to actual temperature

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Aging thermistor, Poor sensor contact with mounting surface, Control board calibration drift, Wiring resistance affecting reading

Safety first: Unplug the freezer before testing sensors.

Verify with thermometer: Place a reliable thermometer in the freezer and compare after several hours.
Inspect sensor mounting: Ensure the thermistor is firmly clipped to the evaporator or wall as designed.
Test thermistor: Measure resistance and compare to the temperature chart on the tech sheet. Replace if out of spec.
Control board: If the sensor is accurate but display remains off by a large margin, the control board may need replacement.
